alternative is go pasar malam see if ppl let go cheato reactor... from wat i see fellow reefer harvest from reactor is thick and lush, is good option imo, but u need to look out for the light i recommend should radiate from center, i got DIY before using two little fishy phosban reactor and just shine light from outside, not very good cos green hair algae start growing on the reactor wall and block the light...my 2 cents lah..
